Monitor Style Shop, With Living Quarters

I know their has been some threads on here before but, I have a question for you guys. Can you build a monitor style shop in the mountains? What happens when the snow slides off the upper roof and lands on the lower roof? Will that cause damage to the lower roof or what. My son is looking at some property in the Blue Mtns, and the elevation is 4029 feet. Typically get 4 or 5 feet of snow. Any advice would be welcomed Thanks.......
